Flat US Plug AC 80-300V LCD Digital Voltmeter Voltage Measuring Monitor, AC 110V 220V Voltage Panel Power Volt Test Monitor Gauge Meter for Household Plug into Outlet to Measure Voltage (1)

Easy to read.

And make it nice when I use my generator to see if I am within tolerances of voltage on my appliances

Great alternative to using a more complicated multimeter. If you just want to know the voltage go with this.

These are a great way to keep an eye on the voltage level at your home outlets. The power company will typically raise the voltage in the summer to offset the increased powered used by air conditioners and pools etc.

I liked the simplicity of the product - simply plug it in. It only takes up one outlet slot, and the readings are large enough to be read at a distance. Although I did not measure the absolute accuracy of the reading, all three units had the same reading. Haven’t had the devices long enough to assess longevity. For me the value was worth the price.

Works really nice

all good

This is great for rvs to make sure the park has proper voltage.

I keep one in the kitchen and one in the RV to just keep an eye on voltage drops from overloading the circuits. Makes a nice little night light, too. Handy, useful and well worth the cash.

These are exactly what I need. New construction and I was wondering if the electrical was up to snuff. And I found out that it is! No brain power needed to install - just plug it in! Once our house project is finished I plan on using in the RV to check on voltages as we travel.
